Purchase CRT as guest flow

[dmtrjsg]

Context

It was reported on the creator roundtable call that there are barriers to purchase CRT tokens for crypto non-natives. The barriers are not unique for our app, and generally apply for the industry but we should make an effort to cater for such audience in favour of higher CRT purchase rate.

Scope

Review current flow of purchaseing CRTs as a guest user and evaluate where UX/ UI changes can facilitate this flow better.

1. Add BUY JOY link right to the Purcahse CRT flow modal when balance is 0.
2. Add Guardarian On-ramp flow as a way to purchase token using fiat
3. Add more ways to buy JOY token (like CEX/ Dex)
4. Find the best way for user to select between ChangeNow, Guardarian, Redirect to CEXs.
5. Review Portfolio UI for purchasing JOY and CRT tokens (e.g. move away from three dots on JOY token balances and display "BUY JOY" button instead that is easily discoverable.(think mobile users)
